Fasting and postprandial serum gastrin levels before and after highly selective gastric vagotomy, truncal vagotomy with pyloroplasty and truncal vagotomy with antrectomy: is there a cholinergic antral gastrin inhibitory and releasing mechanism?

Fasting serum gastrin levels and postprandial gastrin response were measured before and 1 month after highly selective vagotomy, truncal vagotomy with pyloroplasty and truncal vagotomy with antrectomy. The three groups of patients, 12 in each group, were closely matched for age, sex, maximum acid output and completeness of vagotomy. After highly selective and truncal vagotomy an identical and significant increase in fasting gastrin was observed, whereas after truncal vagotomy with antrectomy the pre- and postoperative fasting gastrin levels were not different. The net postprandial gastrin output over basal value was significantly increased after highly selective vagotomy, unchanged after truncal vagotomy and significantly lowered after truncal vagotomy with antrectomy. These results suggest the presence in the intact subject of a cholinergic inhibitory mechanism in the gastric body and fundus for the release of antral gastrin in the fasting and postprandial states and a possible cholinergic facilitatory mechanism for the release of antral gastrin after meals.

Canine gallbladder bile. Effects of proximal gastric vagotomy, truncal vagotomy, and truncal vagotomy with pyloroplasty on volume and composition.

Three groups of four dogs each underwent proximal gastric vagotomy, truncal vagotomy, or truncal vagotomy with pyloroplasty. Two dogs had sham operations. Gallbladder bile was aspirated and measured. Aliquots were cultured and assayed for cholesterol, phospholipid, and bile salts initially and at subsequent laparotomies. Both truncal vagotomy groups showed marked increases in aspirate volume at subsequent laparotomies. The sham and proximal gastric vagotomy groups showed a small initial decrease in mean aspirate volume without further significant changes. When the bile assay data were plotted on triangular coordinates, all point for all groups remained well within the area of cholesterol solubility. Nevertheless, two dogs in each truncal vagotomy group were found to have gallstones. No stones were found in the sham and proximal gastric vagotomy groups. Proximal gastric vagotomy appears to preserve fasting gallbladder bile volume and does not alter bile composition in the dog.

Proximal gastric vagotomy compared with vagotomy and antrectomy and selective gastric vagotomy and pyloroplasty.

A prospective, randomized study of proximal gastric vagotomy without drainage (PGV) was done in 174 adult men with chronic duodenal ulcer intractable to medical therapy. PGV was randomized against truncal vagotomy with antrectomy (TV + A) and against selective gastric vagotomy with Finney pyloroplasty (SGV + P). Postgastrectomy sequelae (dumping, diarrhea and reflux gastritis) were less after PGV. One patient after PGV developed a recurrent ulcer as did one patient after SGV + P. Two patients developed gastric ulcers after PGV. Good to excellent results (Visick I and II) were obtained in 96% of patients with PGV, 94% with TV + A and 86% with SGV + P. Follow-up studies were from six months to four years.

The relative effects of lesser curvature vagotomy and esophageal vagotomy on the acid secretory effect of proximal gastric vagotomy.

Proximal gastric vagotomy is an operation consisting of division of all vagal fibers to the acid-secreting portion of the stomach. These fibers are usually divided along the lesser curvature of the stomach; however, because of a high rate of duodenal ulcer recurrence in some series, it has become apparent that it is important to divide the vagal fibers to the stomach leaving the main vagal trunks along the distal 5 cm of esophagus in order to achieve both adequate control of acid secretion and also a lower duodenal ulcer recurrence rate. The data presented in this study of ten mongrel dogs suggest that, in the dog, division of the vagal fibers along the lesser curvature is more important in reducing acid secretion than is esophageal vagotomy; but the data also emphasize the contribution of the vagal fibers along the distal esophagus since a marked reduction in 2 DG-stimulated acid secretion can only be achieved by dividing the vagal fibers around the distal esophagus as well as those along the lesser curvature.

Results of elective duodenal ulcer surgery in women: comparison of truncal vagotomy and antrectomy, gastric selective vagotomy and pyloroplasty, proximal gastric vagotomy.

This study provides a retrospective comparative analysis of results in 90 women patients who underwent three different elective operations for intractable duodenal ulcer disease. Group I (30 patients) underwent truncal vagotomy/antrectomy (TV + A); group II (30 patients) gastric selective vagotomy/pyloroplasty (GSV + P); and Group III proximal gastric vagotomy (PGV). There were no operative deaths among the 90 patients. No patient after TV + A has developed a recurrent ulcer. Two recurrent ulcers developed after GSV + P, and one gastric ulcer occurred after PGV. Dumping, diarrhea, and reflux gastritis were lower after PGV than with TV + A and GSV + P. Follow-up studies have been from six months to ten years. The clinical results among the three groups of women patients compare favorably with results obtained in a recent prospective randomized study using the identical operative procedures in three groups of men patients operated upon for intractability. There was no statistically significant difference between women and men after similar operative procedures, but the postgastrectomy sequelae were less after PGV in both women and men patients.

Effect of proximal gastric vagotomy and truncal vagotomy and pyloroplasty on gastric functions and growth in puppies after massive small bowel resection.

The effects of truncal vagotomy and pyloroplasty and proximal gastric vagotomy on gastric acid hypersecretion, hypergastrinemia, and growth after massive bowel resection were studied in beagle puppies. In puppies with 80% enterectomy, neither type of vagotomy alters significantly the postprandial hypersecretion of acid from the Heidenhain pouch or the concentration of serum gastrin. Proximal gastric vagotomy tended to decrease the hypersecretion more than did truncal vagotomy. In beagle puppies undergoing 70% small bowel resection, growth was significantly decreased but survival was not impaired. Neither proximal gastric vagotomy nor truncal vagotomy and pyloroplasty reversed completely the impaired growth produced by massive resection. Proximal gastric vagotomy caused a small improvements in growth, while truncal vagotomy and pyloroplasty resulted in a slight decrease in growth. It remains possible that proximal gastric vagotomy could be of value in the management of growing infants with hypersecretion of acid due to short bowel syndrome.

Effects of truncal, selective, and highly selective vagotomy on glucose tolerance and insulin secretion in patients with duodenal ulcer. Part I-Effect of vagotomy on response to oral glucose.

An oral glucose tolerance test was performed in patients who had undergone truncal vagotomy and pyloroplasty, bilateral selective vagotomy and pyloroplasty, or highly selective vagotomy without a drainage procedure at least six months earlier. The results were compared with those from patients with chronic duodenal ulcer before operation. In all three groups of patients after vagotomy more rapid rates of rise of blood glucose and higher peak concentrations were observed than in patients who were tested before operation. These differences were statistically significant only in patients who had undergone truncal or selective vagotomy with pyloroplasty and were probably due to more rapid rates of gastric emptying after these operations. Plasma insulin concentrations were lower after truncal vagotomy than after selective or highly selective vagotomy, the difference between truncal vagotomy and highly selective vagotomy being statistically significant. Truncal vagotomy resulted in a diminished insulin response to oral glucose, which could have been due to vagal denervation of the pancreas or, more probably, impaired release of small-bowel hormones which normally augment the pancreatic insulin response.

The effect of vagotomy antrectomy or vagotomy pyloroplasty on the response of the antrum to meat extract in duodenal ulcer patients.

In 9 normal and 42 duodenal ulcer patients, acid and gastrin studies were performed. Basal, Oxo and Histalog stimulated acid secretion was conducted on each patient. In 24 patients post vagotomy pyloroplasty or vagotomy antrectomy, these studies were repeated within three months after surgery. Two groups of duodenal ulcer patients were identified; those who did respond and those who did not respond to Oxo stimulation. In the "responders," Oxo stimulated acid output and gastrin secretion increased significantly over basal values. Both vagotomy pyloroplasty and vagotomy antrectomy caused a similar significant decrease in Oxo and Histalog stimulated acid output. In two patients with incomplete vagotomy, antrectomy, but not pyloroplasty abolished the Oxo stimulated acid response. These data suggest that OXO stimulation test can select patients with a significant antral component in whom vagotomy and antrectomy would be the appropriate procedure. Our results also indicate that antrectomy will protect against recurrent ulceration in patients with incomplete vagotomy and may explain the lower incidence of stomal ulceration in patients with vagotomy antrectomy, compared to vagotomy pyloroplasty.

A controlled, randomized trial of highly selective vagotomy versus selective vagotomy and pyloroplasty in the treatment of duodenal ulcer.

The results of highly selective vagotomy without drainage and selective vagotomy with pyloroplasty for duodenal ulcer were compared in a randomized, controlled trial of a series of 100 patients. The frequency of dumping, diarrhoea, and epigastric fullness was significantly lower after highly selective (6, 6, and 8 percent) than after selective vagotomy (30, 20, and 28 percent) one year after the operations. Recurrent and persisting duodenal ulcers appearing from one to four years after the operations were significantly more frequent after highly selective (22 percent) than after selective vagotomy (8 percent). No significant relationships were found between recurrent ulceration and gastric acid secretion measurements after the two operations. The Hollander response was early positive in 28 percent and late positive in 30 percent of the patients subjected to highly selective vagotomy, while the corresponding figures after selective vagotomy were 26 and 32 percent. The overall clinical results of the two operations were not different according to the classification of Visick. Excluding the patients with recurrence resulted in significantly better clinical results after highly selective vagotomy.

Interrelations between serum gastrin levels, gastric emptying and acid output before and after proximal gastric vagotomy and truncal vagotomy and antrectomy.

In a prospective study of proximal gastric vagotomy and truncal vagotomy and antrectomy measurements were made, before and after operation, of acid output, gastrin output and gastric emptying of a solid and a liquid meat extract meal. No relationships were demonstrable between acid output and gastrin output. Truncal vagotomy and antrectomy (TVA) produced rapid early emptying of both meals combined with gross prolongation of the overall emptying of the solid meal. Truncal vagotomy and antrectomy reduced the intergrated gastrin output after either meal. Proximal gastric vagotomy (PGV) produced rapid early emptying of the liquid meal with no alteration in the early emptying of the solid meal; however, overall solid meal emptying was delayed. Proximal gastric vagotomy increased basal, peak and integrated gastrin output. In preoperative patients slow solid meal emptying was associated with higher gastrin output but after PGV the reverse was found, the slowest emptiers having the lowest gastrin output. These findings do not support the contention that a pyloroplasty should be added to PGV to reduce the hypergastrinaemia produced by the operation.

Laparoscopic posterior truncal vagotomy and anterior highly selective vagotomy--a case report.

Laparoscopic vagotomy provides a viable alternative to expensive long-term treatment with H2 antagonists in patients with intractable peptic ulcer disease. The minimally invasive procedure offers reduced postoperative discomfort and improved cosmesis. Here, we report our first case of a posterior truncal vagotomy and anterior highly selective vagotomy performed laparoscopically for the first time in Asia. The surgery was uneventful. Diet was resumed on day 3 and the patient was discharged on day 4. Post-vagotomy acid secretion tests on the third week revealed a dramatic decrease in acid production. With further experience, laparoscopic vagotomy can be an attractive alternative to long term medication in peptic ulcer disease.

Gastric emptying following vagotomy and antrectomy and proximal gastric vagotomy.

Gastric emptying of solid meals labelled with 129Cs was studied in patients for up to one year after vagotomy and antrectomy or after proximal gastric vagotomy. Significant delay was found one month after vagotomy and antrectomy but this had returned to normal by six months. No delay was found after proximal gastric vagotomy. The effect of posture on gastric emptying was also studied in the same subjects. No significant differences were found between gastric emptying in the supine or sitting positions after solid meals.

Highly selective vagotomy plus dilatation of the stenosis compared with truncal vagotomy and drainage in the treatment of pyloric stenosis secondary to duodenal ulceration.

Twenty-three consecutive patients with duodenal ulceration complicated by pyloric stenosis who came under the care of one surgeon were treated by highly selective vagotomy (HSV) combined with digital dilatation of the stenosis through a gastrotomy. No form of drainage procedure was used. Thus the antral "mill" and the pyloric sphineter were left intact. Since the stenosis is usually distal to the pylorus rather than truly pyloric such dilatation does not damage the pyloric ring, although it may on occasion lead to perforation of the first part of the duodenum. The subsequent progress of these patients was compared with that of a similar, consecutive series of 23 patients with pyloric stenosis who were treated by truncal vagotomy with a drainage procedure by other surgeons on the same surgical unit. Patients were followed up for between four months and five years. The clinical assessment was carried out in "blind" fashion at a special gastric follow-up clinic. No evidence of recurrent ulceration was found in either group of patients. Two patients from each group subsequently came to reoperation for the relief of gastric stasis. Twenty-two of the 23 patients (96%) who had undergone HSV plus dilatation eventually achieved a good-to-excellent clinical result (Visick grades 1+2), wheras only 17 of the 23 patients (74%) who had undergone truncal vagotomy with drainage achieved such a result. The main clinical difference between the two groups was that side effects such as diarrhoea and abdominal pain or discomfort were more common after vagotomy with drainage than after HSV. These results bear witness to the remarkable propulsive powers of the gastric antrum after HSV, which were evidently sufficient to overcome any tendency to re-stenosis in more than 90% of patients. The 9% incidence of failure due to re-stenosis could perhaps be avoided if a small duodenoplasty were performed instead of simple digital dilatation. The results support the hypothesis that damage to the antral mill and pyloric sphincter can be avoided in the course of operations for "pyloric" stenosis secondary to duodenal ulceration. Avoidance of the drainage procedure is of benefit to the patient, just as it is in patients who have duodenal ulceration without stenosis.

Clinical results of parietal cell vagotomy and selective vagotomy with pyloroplasty in the treatment of duodenal ulcer. Two-year follow-up of a prospective randomized study.

Fifty patients were randomized in a consecutive series of parietal cell vagotomy (PCV) and selective vagotomy with pyloroplasty (SV +P) in the treatment of duodenal ulcer. There were no operative deaths, and the length of the hospital stay and time off from work were the same in both groups. The clinical results were evaluated at 1 and 2 years after operation. Within the first 3 years there were two recurrences after PCV and three after SV +P. The overall clinical result 2 years after surgery did not significantly differ between the two groups; 16/24 after PCV and 17/23 after SV +P classified as excellent results (Visick I). Significantly fewer patients had dumping after PCV (3/23) than after SV +P (13/22). No patient had diarrhoea postoperatively. It is concluded that parietal cell vagotomy gives less dumping than selective vagotomy with pyloroplasty. It is, however, too early to say whether the overall clinical result in a long-term follow-up favours PCV rather than SV +P.
